5 1 : Overview MagneW 3000 Hyper-Fill is developed for high speed batching and filling machine applications. Hyper-Fill is a magnetic flowmeter optimized for the sophisticated measurement demands found in filling applications. Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill 1

6 Overview 2 : Instrument installation Azbil Corporation 2-1 : Converter installation (1) Mount the converter by four M4 screws. (M4 screws are not supplied with the converter.) (2) Rubber bush is attached to the bracket. Tighten the screws through the rubber bush and mount the converter. Handle the rubber bush with care because the rubber bush isolates the converter housing from the mounting wall. (3) Locate the converter so that switches and terminals face to the front for easy maintenance. (4) One converter includes maximum four main boards. Each main board drives each detector.

Do not mount the converter where water splashes. 2 Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill

7 Azbil Corporation Overview 2-2 : Detector Installation (1) Install the detector in the following environment. Ambient temperature: 5 to 50ºC Humidity: 5 to 100% RH (2) The model MGR11U detector is designed using a standard one inch IDF clamp connection. We recommend to use the welding ferrule that Azbil Corporation supplies. For the accurate measurement, pipe inner diameter and ferrule inner diameter connected to the model MGR11U detector should be 15 mm ±0.2 mm. (3) The detector should be mounted so that the FORWARD end of the flow arrows, shown on the detector case and water-proof cover, points in the direction of flow through the tube. (4) By connecting the special cable model MGA23W, the detector keeps waterproof performance. Do not splash water before connecting the model MGA23W cable. (5) After connecting the model MGA23W cable, tighten the screw of the water-proof connector and tighten the belt of the water-proof cover to keep water and moisture away. (6) Detector should be installed where the flowtube will be filled with the fluid and no air/bubbles will be entrapped. (7) Install metal pipes to both upstream and downstream side of the detector. To ensure accurate measurement, install the detector a minimum 15 straight pipe diameters upstream and two pipe diameters downstream from both ends of the detector. 15 straight pipe diameters upstream: (upstream side pipe length: 225 mm minimum) Two straight pipe diameters downstream: (downstream side pipe length: 30 mm minimum) If insulation material tube, such as Teflon tube is installed in upstream side, a minimum 20 straight pipe diameters (300 mm minimum) of metal pipe should be attached to the upstream of the detector. (8) To ensure precise measurement, inner pipe diameter should be 15mm +/-0.2mm. Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill 3

11 Azbil Corporation Overview : Master-slave wiring If the Hyper-Fill flowmeter is installed more than five units, Hyper-Fill flowmeters consist of one master converter and slave converters. Number of units of the detector Number of unit of the Master converter Number of unit of the Slave converter One to four units One unit Zero More than five units One unit One unit or more To ensure accurate measurement, the magnetic interference should be negligible in the multiple head filling machine applications. Master-slave cable carries synchronized signal for excitation so as to minimize magnetic interference. Each converter should be connected with the Master-slave cable.

12 Overview 3 : Configuration of the converter Azbil Corporation Refer to the following configuration table printed to the main unit for the converter configuration. 100mL/s S2 200mL/s 400mL/s RANGE 800mL/s 800mL/s 400mL/s 200mL/s 100mL/s RANGE S3 S4 0.1mL/P 0.05mL/P 0.1mL/P 0.05mL/P 0.1mL/P 30μs 200μs 0.05mL/P 0.1mL/P PULSE WEIGHT PULSE WIDTH Figure : Range Select an appropriate range. It is recommended to set a range so that the flow rate is approximately 70%. Do not set a range of which the flow rate is less than 25%. Select the range by receptacles in S2 shown in Figure : Pulse scale Range 100 ml/s 200 ml/s 400 ml/s 800 ml/s 0.1 ml/p or 0.05 ml/p is selectable as a pulse scale. Pulse scale of 0.05 ml/p is not applicable in case of range of 800 ml/s. Range 100 ml/s 200 ml/s 400 ml/s 800 ml/s Pulse span frequency fs 0.05 ml/p 2000 Hz 4000 Hz 8000 Hz * N/A 0.1 ml/p 1000 Hz 2000 Hz 4000 Hz 8000 Hz * ~Note * Pulse width of 200 μs is not applicable in case that pulse span frequency fs is 8000 Hz. 8 Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill

13 Azbil Corporation Overview 3-3 : Pulse width 30 μs or 200 μs is selectable as a pulse width. Pulse width Tolerance 3-4 : Drop out 30 μs 30 μs ± 4 μs 200 μs 200 μs ± 22 μs Transient response of pulse output: 5 μs typ Pulse width of 200 μs is not applicable in case that pulse span frequency fs is 8000 Hz. (refer to 3-2 : Pulse scale ) Adjustable from 0 to 10% of setting range. This function is used to set the dropout value for the pulse output. The pulse output will be cut off below the setting value to avoid flow pulsation in range value close to zero, thus preventing incorrect totalization of the flow rate. Pulse counting pauses when the flow rate reaches this preset percentage of the set range. Drop out is set by adjusting variable resistor. Default setting is approximately two percent. If pulse is still output even though the valve is shut off, fluid may pulsate. Set the drop out value as approximately five percent.

14 Overview Azbil Corporation 3-5 : Master/slave configuration This function is used to minimize magnetic interference by detectors installed closely each other in the multiple head filling machine applications. A master converter sends synchronized signal for excitation to slave converters, thus avoiding output error due to magnetic interference. According to the model number selected, the configuration for a master or slave is done by the factory. Master converter: MGR13C-**M Slave converter: MGR13C-**S In case of configuring master/slave function, follow below procedure. (1) Turn OFF the power. (2) Loosen screws of the main unit fixed in slot 1 and remove the main unit. (3) Set the DIP switch as shown in the Figure 6. M S Master converter Slave converter Figure 6 10 Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill

15 Azbil Corporation 4 : Operation Overview 4-1 : Warm-up After configuration, follow below procedures before operation. Turn ON the power. For accurate measurement, the electronics needs 30-minute warm-up time to stabilize. Once turn OFF the power and turn ON the power again, wait for 10-minute for electronics warm-up. In this case, remove bubbles and verify no bubbles remain inside of the flowtube. Bubbles will prevent accurate measurement. 4-2 : Zero adjustment A zero adjustment is very important for accurate flow rate measurement. Follow the procedures according to the version of the main unit. Version 1 (ZERO: Variable resistor) Version 2 Version 2 (PLS ZERO: button) Figure 7 Version 1 (ZERO: Variable resistor) (1) Fill the fluid inside of the flowtube and verify the fluid stops. (2) Zeroing the flowmeter. Connect a digital voltmeter or tester between CHECK+ and CHECK- terminals of the main unit. Adjust the variable resistor so that the voltage measured by the digital voltmeter becomes 0 ±20 mv. Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill 11

16 Overview Azbil Corporation Version 2 (PLS ZERO: button) (1) Fill the fluid inside of the flowtube and verify the fluid stops. (2) Zeroing the flowmeter. Push the button of the PLS ZERO for one second. Zero adjustment will be done automatically. If zero adjustment is done successfully, LED lights out for five seconds then light on. If failed, LED blinked for 20 seconds. Check if wiring is correct and no bubble remains in the flowtube, and try zero adjustment again. LED operation in case of correct zero adjustment 1s 5s LED operation in case of incorrect zero adjustment 1s 20s blink Figure 8 Version 2 is compatible with Version 1. Version 1 can be replaced with the version : Span adjustment Span adjustment was performed at the factory. If there is some discrepancy between actual filling value and flowmeter measured value, tune the span by the SPAN variable resistor. 12 Model MGR13C/MGR11U - MagneW3000 Electromagnetic FLowmeter Hyper-Fill
